Abstract

With the rapid development of modern electronic information technology, wireless ordering systems have a huge application market in the catering industry. By replacing the traditional paper and pen, the wireless ordering system can provide more humanized ordering services, which is an important means for catering enterprises to improve management level and work efficiency.
This paper is based on STC89C52 microcontroller and uses wireless communication technology to design a wireless ordering system. The main functional modules of this paper include: single-chip microcomputer main control module, wireless communication module, LCD display module, voice module, input module and APP. The sender microcontroller orders food as a client, and transmits the ordering data or reminder signal to the receiving MCU of the merchant through NRF24L01. The microcontroller processes the data for price settlement and sends the order to the LCD display. Using the voice broadcast module decoding, the order is voice-broadcast by calling the macro definition of the corresponding audio. The system can shorten the time of ordering, placing and paying, improve the efficiency of restaurant dining, and increase the satisfaction of customers with restaurant service. This system has a very broad application and use development prospects.
